My collection of Mac Book Pros have achieved a 100% failure rate. Well, 125% considering one of them failed, was repaired, then failed again. The latest is a 2015 model due to a swelled battery. Unfortunately, this is one of the models with it glued in and requires completely disassembly to replace it. After disassembly I found it can't be removed without some sort of solvent. I also had to remove a whole bunch of screws (probably at least 6 different sizes, and I didn't keep track of where they go). Anyway, I stripped out what I want to keep (the drive and airport/bluetooth card), will probably just junk the rest at the recycling center. Lion batteries are hazardous, wouldn't want it to explode into flames. I suppose I could try saving the screen and logic board, but I have my doubts that 10 year old parts are in much demand.
